I think I can hear a vacuum cleaner LOL
If by bombed you mean ability to run consistent 10s then yes. Car was engineered but when I changed the intake it was too loud (92dB), I learnt from the mistake and stuck to regulations, I had no guidance and I did not modify my car with the intent for it to be 2dB over the permissable limit. I hate seeing people decatting on the street, these kind of things give the authorities even more reason to screw over every modified car owner. Noise pollution is one thing, but intentionally releasing damaging gasses into the environment for the sake of gaining negligable power is another. All im saying is don't be stupid.
p.s. If you want advice, why not call 1 of the couple thousand exhaust specialist stores across Australia... I'm sure you will get an accurate answer without feeling threatened.
